AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
354 AM EDT TUE JUL 17 2012

.SYNOPSIS...
HOT AND HUMID WEATHER WILL PERSIST THROUGH WEDNESDAY. A COLD FRONT
WILL BRING A ROUND OF SCATTERED SHOWERS AND THUNDERSTORMS
WEDNESDAY INTO WEDNESDAY NIGHT WHICH WILL BREAK THE HEAT AND
HUMIDITY. SEASONABLE TEMPERATURES AND LOWER HUMIDITY WILL FOLLOW
THURSDAY INTO NEXT WEEKEND AS A HIGH PRESSURE BUILDS IN FROM
CANADA. WARMER AND MORE HUMID CONDITIONS WILL RETURN NEXT MONDAY.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
WEAK HIGH PRESSURE BUILDS OVER THE REGION. ALTOCUMULUS MOVING FROM
THE GREAT LAKES MAY PROVIDE SOME CLOUDS...BUT STILL SUFFICIENT
SUN TO EXPECT FULL MIXING. MODEL MIXING DEPTHS REACH 7000 FEET.
TEMPS AT 850 MB REACH 20-21C WHILE 800 MB TEMPS REACH 16-17C
/EQUIV TO 21-22C AT 850 MB/. SO IF WE DO GET FULL MIXING THEN
FORECAST MAX TEMPS OF 95-97F ARE QUITE REASONABLE AND CAN/T RULE
OUT A 98-99F.

COMBINE THE HEAT WITH DEWPOINTS IN THE UPPER 60S AND LOW 70S THAT
LEADS TO APPARENT TEMPS OF 100-103F. THESE VALUES...WHILE NOT
COVERING EVERY SQUARE FOOT OF SOUTHERN NEW ENGLAND...DO COVER
PARTS OF MOST OF THE FORECAST AREA. THE REGIONS NOT COVERED ARE
THE EAST SLOPES OF THE BERKSHIRES/SOUTH COAST AND ISLANDS. MOST OF
THE CENTRAL HILLS ARE OUTSIDE...BUT LOWER PARTS OF CHESHIRE-
HILLSBOROUGH-WORCESTER-WINDHAM DO REACH CRITERIA. WE PLAN TO
ISSUE A HEAT ADVISORY WITH THIS PACKAGE FOR MOST OF SOUTHERN NEW
ENGLAND...LEAVING OUT THE EAST SLOPES OF THE BERKS...AND THE SOUTH
COAST EASTWARD FROM NEWPORT.

THE OTHER CONCERN IS CONVECTION. THE STRONG HEATING EXTENDS DEEP
INTO THE ATMOSPHERE. TEMPS AT 700 MB ARE FORECAST TO REACH 10C
SOUTH OF THE MASS PIKE AND COME CLOSE IN NORTHERN AREAS. LAPSE
RATES ALOFT WILL BE MEDIOCRE WITH 850-500 MB VALUES AROUND
6C/KM...MAY A LITTLE STRONGER TOWARD EVENING. THE UPPER JET WILL
BE WELL NORTH OF THE REGION SO UPPER VENTING WILL BE SMALL. BUT
THERE WILL BE A LOT OF MOISTURE WITH PCPBL WATER VALUES BETWEEN
1.75 AND 2.00 INCHES. WE WILL CONTINUE TO MENTION SLIGHT CHANCE
POPS IN SOUTHERN NH AND FAR NORTHERN MASS WITH POPS LESS THAN 15
PCT FARTHER SOUTH.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM WEDNESDAY/...
TONIGHT...
ANY CONVECTION SHOULD FALL APART QUICKLY TOWARD SUNSET. DEWPOINTS
WILL REMAIN NEAR 70 WITH DIMINISHING WIND...SO POTENTIAL FOR FOG
AREAS WITH POOR VSBYS.

WEDNESDAY...
A COLD FRONT CURRENTLY OVER THE GREAT LAKES WILL DROP SOUTH ACROSS
SOUTHERN NEW ENGLAND. LOW CONFIDENCE ON THE MORNING POSITION OF
THE FRONT...BUT MODEL CONSENSUS WOULD PLACE IT ALONG THE MASS/NH
BORDER. MOTION SOUTH WOULD BE SLOW...MODEL CONSENSUS PLACES THE
FRONT ALONG THE SOUTH COAST IN THE EVENING.

TEMPS ALOFT REMAIN QUITE WARM WITH AFTERNOON TEMPS AT 850 MB
17-19C. CLOUDS ALONG THE FRONT MAY INTERFERE WITH FULL
MIXING...BUT EXPECT ENOUGH HEATING TO BRING MAX TEMPS TO AROUND
90S OR INTO THE LOWER 90S. THIS MAY BE LOW ENOUGH TO ESCAPE
ANOTHER HEAT ADVISORY...BUT IT WILL STILL BE WARM AND MUGGY.

WITH A FRONT IN THE NEIGHBORHOOD THE QUESTION TURNS TO CONVECTION.
MID LEVEL TEMPS ARE EXPECTED TO COOL A LITTLE...ELIMINATING THE
THREAT OF CAPPING. STABILITY PARAMETERS WILL BE UNSTABLE WITH
SHOWALTER ROUGHLY -2 TO -4 WITH LOWEST VALUES SOUTH OF THE MASS
PIKE...AND CAPES ARE FORECAST 1000-2000 IN NORTHERN MASS AND
2000-3000 IN CT-RI-SE MASS. UPPER TROUGH DIGGING OVER THE
NORTHEAST WILL BRING THE UPPER JET CLOSER TO THE REGION. MID LEVEL
LAPSE RATES REACH 6.5C/KM ALONG THE SOUTH COAST BUT TREND LESS
FAVORABLE FARTHER NORTH. PUT IT ALL TOGETHER...WE EXPECT CHANCE
POPS ALL AREAS...HIGH-END CHANCE POPS IN THE SOUTH TRENDING LOWER
FARTHER NORTH.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/...
HIGHLIGHTS...

* THUNDERSTORMS/SHOWERS LINGER INTO EARLY THU
* MORE SEASONABLE TEMPS WITH LOWER HUMIDITY THU THROUGH THE
  WEEKEND

OVERVIEW AND MODEL PREFERENCES...
17/00Z MODEL GUIDANCE IN FAIR AGREEMENT THROUGH THE LONG
TERM...PARTICULARLY WITH THE PROGGED SYNOPTIC SCALE PATTERN SHIFT
LATE IN THE WEEK AND THE WEEKEND... A TREND TOWARD A NEAR NEUTRAL
TO WEAKLY POSITIVE PNA PATTERN WITH A DIGGING/DEEPENING TROF OVER
ERN CANADA. THIS SUPPORTS DRY NW FLOW /A FEATURE ON ALL LONG
RANGE GUIDANCE/ LATE IN THE WEEK AND THE WEEKEND.
OTHERWISE...THERE ARE SOME SLIGHT TIMING/QPF DIFFERENCES WITH THE
COLD FRONT SAGGING S OF THE REGION AROUND MID WEEK...BUT THE
DRYING TREND THEREAFTER IS GENERALLY WELL AGREED UPON.
THEREFORE...WILL CONTINUE TO FAVOR THE SLOWER TIMING OF THE COLD
FRONT WITH A FOCUS ON THE ECMWF AS A BASELINE THROUGH THE MID
TERM...THEN TREND TOWARD A DRY ECMWF/CMC BLEND AS A BASELINE
THROUGH THE WEEKEND AS THE GFS AND MANY OF ITS GEFS MEMBERS ARE
ATTEMPTING TO CREATE DIURNAL QPF IN A VERY UNFAVORABLE
ENVIRONMENT.

DETAILS...

WED NIGHT INTO THU...
SFC COLD FRONT WILL BE GRADUALLY SHIFTING S OF THE REGION THROUGH
THIS PERIOD. WHILE THERE ARE SOME TIMING DIFFERENCES AS MENTIONED
ABOVE...WITH THE FRONT BECOMING NEARLY PARALLEL WITH THE ZONAL
FLOW ALOFT...THE SLOWER TIMING SUGGESTED IN THE ECMWF IS FAVORED.
THEREFORE...BY 00Z THU...THE FRONT WILL BE JUST ALONG THE
IMMEDIATE S COAST OF NEW ENGLAND...THEN SHIFTING TO THE DELMARVA
BY 00Z FRI. THE KEY WITH THIS FRONT WILL BE THE LIFT IT PROVIDES
TO WORK WITH ANY REMAINING INSTABILITY FROM THE DAY WED. IT
APPEARS THAT THE EARLY OVERNIGHT HOURS WED NIGHT...THERE MAY BE
SOME REMNANT SFC BASED CAPE WITH VALUES 1000-1500J/KG...SO EXPECT
AT LEAST THE THREAT FOR THUNDER THROUGH ABOUT 06Z. AFTER THIS
POINT INSTABILITY WILL BE WAINING DUE TO LOSS OF DIURNAL HEATING
AND THE DRIER...COOLER AIR BEGINNING TO SPILL OVER FROM THE N.
LAPSE RATES WILL BE GRADUALLY DECREASING TO VALUES CLOSE TO 5C/KM
BY THU MORNING...SO FEEL THAT TSTM THREAT WILL BE MINIMAL OVER THE
LAND AFTER WED NIGHT.

THE OTHER ISSUE WILL BE THE POTENTIAL FOR DAYTIME CONVECTION
PARTICULARLY OVER THE SRN WATERS AND THE CHANCE FOR SOME ISOLATED
HEAVY RAIN POCKETS IN THE MORE STABLE AIRMASS BEHIND IT. WITH A
FOCUS FOR LIFT PROVIDED BY THE SLOW MOVING FRONT THU...THERE IS
THE CHANCE FOR INSTABILITY INCREASING AGAIN IN THE NEAR FRONTAL
ENVIRONMENT DURING THE DAY WITH SOME NEAR 1000J/KG CAPE ONCE AGAIN
APPEARING. THE FOCUS WILL BE ON THE S COASTAL WATERS HOWEVER...AS
BEHIND THE FRONT THE DRY AIRMASS WILL BE LEADING TO A LOSS OF THIS
INSTABILITY OVER THE LAND. IMMEDIATELY BEHIND THE FRONT WED NIGHT
INTO EARLY THU THOUGH...WILL BE THE THREAT FOR SOME HEAVIER
SHOWERS TO LINGER DUE TO PWAT VALUES TAKING SOME TIME TO DROP FROM
THE NEAR 2.0 INCHES. SO WILL HAVE TO MONITOR THIS THREAT
PARTICULARLY FOR SRN AREAS ALL THE WAY INTO THE DAY THU.

ALL OF THIS ADDS UP TO A PERIOD OF PROLONGED UNSETTLED WX WITH
TSTMS/SHOWERS/HEAVY RAIN PARTICULARLY FOR THE REGIONS S OF THE
MASS PIKE FROM WED NIGHT INTO THU...WITH A TREND TOWARD DRIER AND
SUNNY CONDITIONS FROM N TO S DURING THE DAY.

FRI INTO EARLY NEXT WEEK...
WITH THE PATTERN SHIFTING TO A NEAR NEUTRAL TO POSITIVE PNA
PATTERN THANKS TO A DEEPENING AND DIGGING TROF IN ERN CANADA...THE
FLOW PATTERN WILL BE GENERALLY OUT OF THE NW WITH COOLER AND DRIER
CP DRAW. BROAD UPPER LVL RIDGING THE THE W WILL ALLOW FOR A STRONG
AND SLOW MOVING HIGH PRES TO BUILD OVER THE REGION DURING THE
PERIOD. THIS WILL LEAD TO COOLER/DRIER CONDITIONS THROUGH THE
WEEKEND WITH TEMPS CLOSER TO THE NORMAL VALUES FOR LATE JULY WITH
PLEASANT DWPTS. ATTM...HAVE GONE WITH A DRY FORECAST DESPITE GFS
ATTEMPTING TO GENERATE SOME DIURNAL CONVECTIVE QPF ESPECIALLY OVER
THE WEEKEND. THE DRY COLUMN ON SOUNDINGS FROM THE OPNL GFS AND
OTHER LONG RANGE GUIDANCE FAVOR A DRY FORECAST WITH LITTLE
INSTABILITY AVAILABLE FOR CONVECTION. WILL ALSO DELAY TIMING OF A
SECOND FRONTAL BOUNDARY EARLY NEXT WEEK AS THE GFS IS LIKELY
SHOWING ITS TYPICAL LONG RANGE FAST BIAS...BECAUSE THE ECMWF/CMC
AND MANY GEFS MEMBERS DO NOT BRING IT THROUGH AS QUICKLY.

OVERVIEW...HIGH CONFIDENCE.
VFR TODAY AND TONIGHT WITH PATCHY MVFR/IFR IN LATE NIGHT/EARLY
MORNING FOG. LOW RISK OF AN ISOLATED TSTM ACROSS SOUTHWEST NH AND
POSSIBLY NORTHERN MASS. MODERATE RISK OF TSTMS DEVELOPING
WEDNESDAY ESPECIALLY ACROSS AREAS SOUTH OF THE MASS PIKE. BRIEF
MVFR/IFR CONDITIONS WITH ANY TSTMS.

KBOS TAF...HIGH CONFIDENCE. VFR. INCREASING SOUTHWEST WIND WILL
KEEP THE SEA BREEZE FROM DEVELOPING.

KBDL TAF...HIGH CONFIDENCE. VFR.

OUTLOOK...WEDNESDAY NIGHT THROUGH SATURDAY...

WEDNESDAY NIGHT...MODERATE CONFIDENCE. ANY TSTMS WILL BECOME
FOCUSED NEAR THE S COAST WITH PERIOD OF MVFR/IFR.

THURSDAY THROUGH SATURDAY...HIGH CONFIDENCE VFR.  BUT LOW PROB OF
LINGERING MVFR CONDITIONS OVER THE CAPE/ISLANDS THU MORNING.

&&

.MARINE...
TODAY...
SW WINDS TODAY WITH GUSTS 15-20 KT. LOW PROBABILITY OF 25 KT NEAR
SHORE. GOOD VSBY WITH JUST A LOW PROBABILITY OF AN AFTERNOON
SHOWER/TSTM NORTH OF CAPE ANN.

TONIGHT...
QUIET WEATHER WITH GUSTY SW WINDS DIMINISHING WITH SUNSET. A 5
FOOT SWELL MAY BUILD ON THE SOUTHERN OUTER WATERS BUT THE
REMAINING WATERS SHOULD STAY BELOW 5 FEET. WILL PUT UP A SMALL
CRAFT FOR HAZARDOUS SEAS ON THE SOUTHERN OUTER WATERS. AREAS OF
FOG AFTER MIDNIGHT WITH LOCALLY POOR VISIBILITY.

WEDNESDAY...
WINDS AND SEAS WILL BE BELOW SMALL CRAFT LEVELS.  SEAS WILL
DIMINISH BELOW 5 FEET ON THE SOUTHERN OUTER WATERS.

OUTLOOK...WEDNESDAY NIGHT THROUGH SATURDAY...

HIGH CONFIDENCE THAT WINDS WILL REMAIN BELOW SCA THROUGH THE PERIOD.
SW FLOW WED WILL SHIFT TO N/NE LATE WED NIGHT INTO THU WITH MAINLY
EASTERLY FLOW PERSISTING INTO SAT.

MODERATE CONFIDENCE FOR SEAS...THERE IS THE CHANCE THAT SEAS WILL
BRIEFLY REACH 5-6 FT OVER THE SRN AND SERN WATERS WED NIGHT INTO
THU...WITH SMALL CRAFT ADVISORIES POSSIBLY NEEDED.

WINDS AND SEAS THEN REMAIN BELOW SCA THRESHOLDS THROUGH THE
WEEKEND WITH HIGH PRES BUILDING OVER THE WATERS.
